Bed bugs: These nasty bloodsuckers can take over your homes in less than a week

Bedbugs as what their name suggests,  start by infesting the place we sleep. They come to your house through you and other members of the family or brought in by visitors. We, humans are the carriers bed bugs.

These blood suckers can turn an entire household into an itchy nightmare in  less than a week.

For the past years, we live peacefully, uninterrupted by these tiny critters of the night or even during the day. They are like fighters trained in guerrilla warfare. They can “bite” and disappear totally in an instant. They are fast crawlers and excellent in camouflage technique.

Just when you think they are gone, they are suddenly back  without warning.

To author Brooke Borel of “Infested,” the recent resurfacing of bedbugs is a growing trend. We can try to exterminate but they come back just the same.   The return of bed bugs, Borel writes, “isn’t a fluke. It is a return to ­normal.”

Eons of years ago, our cave-dweller ancestors used to get along fine with bedbugs, so it seems

As our ancestors left their caves to a more comfortable dwellings into metropolitan cities, a course which took thousands of years, they brought along  these pesky pests with them for a ride. Unsurprisingly, the bugs were able to survive and outlived family members and friends who were not used to the urban life.

These highly urbanized new bugs were more alert at night, when we humans take our nap, and developed  longer, leaner  legs for hopping away quickly.

But the bedbugs evolution is still going on leaving us humans grasping in the dark, literally. They are  still evolving, and in the last decades, they have developed their worst feature of all.  They have become resistant to bug poison.

Bedbugs of today have developed thicker, waxier exoskeletons, which aids in shielding them from poison we spray them and faster metabolism to to beef-up their natural chemical defenses.

Biologist Regine Gries of Simon Fraser University, has spent the last five years researching for a method to eradicate these creatures.  She together with  her team recently discovered the ingredients for a bug-alluring scent that people could use to terminate bed bugs

In World War II, the insecticide DDT was successfully used to poison, and wiping out tons of insects, including bed bugs, Borel writes. But recently, it stopped proving to be effective anymore.

Borel writes, that intercontinental  travel has provided for the bedbug to travel and  spread across the globe, as they hitch a ride in our luggage. Today, they are an international blight.

“In a way, we created the modern bed bug: it evolved to live with us and to follow us,” Borel writes.

What humans intend to do about the these critters remains to be seen.
